Abstract (en)
A method, an apparatus, and a computer program product for wireless communication are provided in which resource elements compatible with multiple different communication protocols, which may not be compatible with one another, may be mapped to a radio frame. For example, in an LTE network, equipment configured to be compatible with 3 GPP release 8 standards (herein referred to as Rel. 8) may have certain limitations as to what bandwidth is available for use and access, while these limitations may not apply to later releases of LTE standards after Rel. 8 (herein referred to as "New"). Thus, a system bandwidth can be extended to include an extension portion, to which resource elements compatible with the New protocol may be mapped, and a non-extension portion, to which resource elements compatible with either Rel. 8 or the New protocol may be mapped, providing an effective multiplexing of system resources.
